There are dozens of email marketing platforms. Most will technically do what you need. The question is which one fits how you actually work, what you need right now versus in a year, and how much complexity you are willing to manage day to day.
Choosing the wrong platform is not a disaster. Migrating away from it is a pain. Choose the right one the first time by being honest about where you are, not where you aspire to be.

Quick Comparison: Which Tool Fits Which Situation
| Tool | Best for | Free tier | Key limitation |
|---|---|---|---|
| Mailchimp | Getting started, simple newsletters | Up to 500 contacts | Automation gets expensive fast as list grows |
| Kit (ConvertKit) | Creators and freelancers running sequences | Up to 10,000 subscribers | Limited visual email design options |
| ActiveCampaign | Behavior-based automation, CRM-connected email | No (free trial only) | Steeper learning curve, higher cost |
| MailerLite | Clean design, solid automation at low price | Up to 1,000 subscribers | Fewer native integrations than competitors |
| Brevo | High volume sending, transactional email alongside marketing email | 300 emails/day | Contact limits, pricing model is per-send not per-subscriber |
If You Are Just Getting Started
Start with Kit (formerly ConvertKit). The free tier goes up to 10,000 subscribers, which means you are unlikely to hit a pricing wall until you are generating meaningful revenue from the list. The interface is simpler than Mailchimp’s and designed around the workflows freelancers and creators actually use: tagging subscribers by interest, sending broadcasts, and building basic sequences.
The limitation is design. Kit’s email builder produces clean, text-forward emails. If your brand relies heavily on visually designed emails with images, columns, and branded color blocks, Kit will feel constrained. For most service businesses, text-forward emails actually perform better anyway. People read them. They do not always engage with heavily designed ones.
Start on Kit’s free tier, build your list to a thousand subscribers, then evaluate whether you need more capability. Many freelancers never need to leave it.
If You Need Behavior-Based Automation
ActiveCampaign is the most capable option at an accessible price for service businesses. Behavior triggers, contact scoring, site tracking, sales pipeline, and a built-in CRM. It does more than any other platform at a comparable price point.
The learning curve is real. Plan on spending a few hours getting the interface organized before you start building automations. The visual automation builder is powerful but not intuitive at first. Once you understand the logic, it becomes the fastest platform to work in for complex sequences.
Worth the investment when you have more than 200 to 300 active contacts and are regularly losing track of where people are in your follow-up process. If proposals are going cold because you forgot to follow up, if hot leads are sitting in an inbox with no next action, if you cannot tell which contacts are engaged and which have gone cold: those are the signs you need behavior-based automation and ActiveCampaign is the right tool.
If Design Matters to Your Brand
MailerLite produces the cleanest-looking emails from its drag-and-drop builder without requiring custom HTML. The template library is limited but well-designed. The automation features are good enough for most service business needs. The price is lower than Mailchimp or ActiveCampaign at equivalent subscriber counts.
If you are a designer, a brand strategist, or any creative whose work is visual, MailerLite lets your emails look like your brand without fighting the builder. That credibility matters when your email is the first impression a prospective client gets of your aesthetic judgment.
Features Worth Paying For vs. Features That Sound Useful But Are Not
Email platforms add features to justify pricing tiers. Not all of them earn their place in your workflow.
Worth paying for
- Behavior-triggered sequences: Sends based on what contacts do, not just fixed time delays. Someone who visits your pricing page gets a different sequence than someone who only opened a newsletter. This is the feature that separates capable platforms from basic ones.
- List segmentation by tag or custom field: Send the right message to the right segment. Blasting your full list with every message is how you train subscribers to ignore you.
- Deliverability tools and reputation monitoring: If your emails are landing in spam, all the automation in the world does not help. Platforms that actively monitor sender reputation and provide tools to improve it are worth the premium.
Sounds useful but rarely used
- Landing page builders: Most people build landing pages on their website and embed the form. The platform’s landing page builder is an emergency backup, not a primary tool.
- Social media scheduling integrations: Email platforms are not good social tools. Use a dedicated social tool if you need one.
- Advanced AI writing features: These exist on most platforms now and require heavy editing before the output is usable. Faster to write your own copy.
Before You Switch Platforms
Switching email platforms is genuinely painful: export your list, clean and reformat it, re-import it, rebuild your sequences from scratch, reconfigure your signup forms, and worry about deliverability during the transition period while your sending reputation transfers.
Before switching, ask yourself whether you have actually hit the limit of what your current platform can do, or whether you have just not learned to use it fully. Most platform limitations people cite are features they have not found yet, not features that do not exist.
Switch only when you can name a specific feature you are missing and will immediately use. “I heard ActiveCampaign is better” is not a reason to switch. “I cannot trigger a sequence based on someone visiting my pricing page and Kit does not support that” is a reason to switch. One is abstract, one is a problem you are actually trying to solve.
